I went German again... just because they had fewer soldiers online at the time.
It was a long night of me sucking badly. The game is so very hard when you're not in a squad, and mine has long since dried up.
Happily, after several missions in various gear all ending in failure, I finally managed to take part in the retaking of a spawn point in Charlerois, and racked up 4 inf kills in my Panzer 3 f before returning safely to base. Sure, squishies aren't the glory a tanker craves, but a kill's a kill.
